Question Suggestions for Merill DCA 5.5

Hi,
I have a pair of nice Merill DCA 5.5 not the current sold DCA 4.

I'm quite impressed by all praises of the tiny zigmahorn!

As I went along in forums like diyaudio ...searched with google...I couldn't find any drawings or similar.


Does anybody know a great cab proposal???



I heard of "BIB" (Bigger is Better ?!)and PAWO Horns - but no concret drawings or pictures.




Please post your suggestions.



I will present the results here later, I will use fine oiled maple wood.

Jochen

I have a pair of those... measured data is on my computer downstairs... but a Merrill customer told me that the parameter spread is high, so mine might not be representative of yours... have you measured the parameters or got them with the drivers?

It took us a long time to find a driver that worked in thse boxes. If the specs on yours are similar to mine, it would be touch & go... These definitly need the supraBaffle.

What Dave forgot to say is that the above driver was the Fostex FE127E

The supra baffle as shown in the posted photo of PAWOs was helpful in reducing reflections from the back panel of the very shallow cabinet (allowing playing with extra felt damping pads immediately behind the driver ). Quite simply we found the system very confused and muddled in the vocal midband area with the driver mounted flush.

Something else interesting to try would be to continue the EnABL pattern treatment on the supraBaffle and main enclosure baffle. We've had one pair of enclosures (FonkenPrime) treated this way, and to my ears, while not as significant an improvement as to the driver cone, it's never the less incremental.

It looks promising in T.C.'s original 69" internal height, driver location BIB except with a ~8.78" width, 12.42" depth if your ceiling height is the ~ 8ft standard.

Default DCA 5.5

If anyone is still interested in a fairly simple Cabinet design for Dave Merrills DCA5.5s I can post some pictures and specs. I have had the drivers in a pair of cabinets I made for some Fostex FE 164s. The Fostex sounded mediocre at best and the cabinets sat in a corner forgotten for about a year and then I bought some of the last drivers Dave had available and didn't have time to throw together a pair of PAWOs so made a set of spacers to mount the smaller driver, hooked them up and have been enjoying them for about a year and a half. I had not realized some of the cabinet designs were not working well until I went searching for more of Daves drivers and discovered the Two Bald Guys were getting a new production run. I have four tube amp setups I have tried these with and also an ARCAM AVR300 and these drivers put to shame any Fostex set up I have tried. Also they compete with my Moth Audio Cicadas and Lowther DX3s. The cabinets are basically a "mini" version of Terry Cains Abby.
